hAP Lite accounting

hello
i have a hAP Lite and i want to connect an ADSL2+ router to it and run these configs on it:
bandwidth limitation for each user or all users the same limit
monthly usage limitations for each user or all users
give them access based on mac address or user pass
how ?
and if i use 2*SXT 5HnD for enhancing the wireless are all those configs still effective ?
thanks
